I managed to attract twin waxwing chicks when I had two incomplete vases in my garden. The first chick didn’t produce any flowers but the second one did. Does that mean the first chick would go to the leftmost vase and if that’s the incorrect chick you still need a second chick for the rightmost vase. That one did produce flowers. I thought if the first chick didn’t work on the first vase it would automatically go to the second.. is this not the case? I hope this makes sense

If you had two vases out, it would go to the furthest to the left which could use it.  If it didn't count for the first vase, the first one spotted would have gone to the second vase.

I suspect the first one dropped the flowers but perhaps your screen didn't refresh?
